How to Survive Cold Water Immersion

Donning a a Gumby cold water survival suit prior to getting wet is my 1st line of defense. I had completely forgotten my wife and I got fitted for them at the AC Boat showing in 2007. Only after cleaning out the Mainship did I realize we still had them and they were in perfect shape. They are now on the Gulfstar with our 406MHz PLBs.I think staying with or on top of the vessel is also important how many times have you read the vessel was found but not the crew?Bill
